Architectural Aluminum Skylight Windows for Global Projects
For over 25 years, Foshan Derka Architectural Doors & Windows Co., Ltd. has designed and manufactured heavy-duty custom aluminum skylight windows for architects, commercial general contractors, hotel purchasing managers, and residential developers worldwide. Operating from our 115,000 m² automated facility in Foshan, China, we deliver complete roof glazing systems engineered to match your local building codes, structural wind-load requirements, and thermal isolation targets.
Our custom skylight windows combine precision-extruded T6063-T5 aluminum profiles with high-performance Low-E insulated glass, specialized continuous EPDM weather-stripping, and integrated water drainage channels to guarantee 100% leakproof security and long-term durability.
Customizable Skylight Window Options
Select from multiple opening mechanisms and structural profiles customized to your roof slope, architectural style, and ventilation requirements.
Fixed Architectural Skylights
Sealed overhead glazing panels engineered to maximize natural daylighting, eliminate thermal leaks, and frame uninterrupted sky views for living rooms, stairwells, and modern atriums.
Motorized Venting Skylights
Electric top-hung or center-pivot roof windows equipped with smart chain actuators, remote operation, and automated rain sensors that trigger auto-closing during sudden rainstorms.
Retractable Sliding Roof Windows
Heavy-duty electric sliding roof systems that move smoothly along motorized tracks, opening full room rooflines for luxury hotel rooftops, sunrooms, and villa patios.
Engineered for Thermal Insulation & Absolute Watertightness
Roof windows are exposed to extreme solar heat, rain impact, and thermal expansion. Our engineering team designs every unit with heavy-duty structural components.

B2B Skylight Procurement Queries
Common technical and ordering inquiries from international contractors, developers, and trade buyers.
Our skylight systems feature a multi-tier defense strategy: primary continuous EPDM rubber seals, internal condensation management gutters, commercial-grade structural silicone bonding, and engineered aluminum step-flashing kits customized to your exact roof cladding type (tile, metal, flat concrete, or shingles).
Yes. We utilize high-grade T6063-T5 aluminum profiles with polyamide (PA66) thermal barrier strips, paired with double or triple-glazed Low-E insulated glass filled with Argon gas to minimize U-factors and Solar Heat Gain Coefficients (SHGC) for tropical or freezing climates.
We integrate electric chain actuators and linear motors compatible with smart home automation systems, wall switches, wireless remotes, and automated rain/wind sensors that trigger immediate auto-closing when weather changes occur.
Every order is made to measure. We support oversized single-pane skylights, multi-panel continuous ridge light rows, pyramid skylights, vaulted configurations, and motorized retractable glass roof systems tailored precisely to your CAD files.
